The **LSRG3392-R6-PF** is an electronic component primarily classified as a **T-1 (3mm) Bi-Color LED (Light Emitting Diode)**. It is designed for indicator applications where multiple states need to be shown using a single lamp. --- ### 1. Technical Specifications The part typically features two different colored chips (Red and Super Green) integrated into a single package. | Parameter | Specification | Details | | :--- | :--- | :--- | | **Package Type** | T-1 (3mm) | Round through-hole mounting | | **Colors** | Red / Super Green | Dual-color capability | | **Polarity** | Common Cathode / Anode | Usually 3-lead configuration | | **Lens Appearance** | White Diffused | Even light distribution | | **Operating Voltage** | 1.8V - 2.4V | Typical Forward Voltage ($V_F$) | | **Luminous Intensity** | ~20 - 80 mcd | Varies by color and current | | **Viewing Angle** | 60 degrees | Wide viewing angle | --- ### 2. Physical Structure & Pinout The "PF" suffix generally indicates that the component is **Pb-Free (Lead-Free)** and RoHS compliant. The pinout structure is critical for circuit design: * **Pin 1:** Anode for Color 1 (e.g., Red). * **Pin 2:** Common Cathode (Longest lead). * **Pin 3:** Anode for Color 2 (e.g., Green). *Note: By powering both anodes simultaneously, the LED can produce a third color (Amber/Yellow) through additive color mixing.* --- ### 3. Circuit Integration To protect the LED, current-limiting resistors must be placed on the anode lines. ```cpp // Typical Calculation for Resistor (R) // R = (V_supply - V_forward) / I_target // Example: 5V supply, 2V LED drop, 20mA current // R = (5 - 2) / 0.020 = 150 Ohms ``` ### 4. Key Applications * **Status Indicators:** Power (Green) vs. Error (Red). * **Networking Equipment:** Link/Activity status on routers or switches. * **Industrial Controls:** Machine state monitoring (Ready/Running/Fault). * **Consumer Electronics:** Battery charging indicators (Charging/Full). ---
